A two-way electromagnetic diaphragm pump

Abstract

The invention discloses a bidirectional electromagnetic diaphragm pump which relates to the technical field of electromagnetic diaphragm pump manufacturing; a diaphragm A and a diaphragm B are connected on both ends of a pump shaft; an armature A and an armature B are symmetrically fixed on the pump shaft; a coil A and a coil B are respectively sleeved outside the armature A and the armature B; a spring A and a spring B are respectively connected on a pump shell and the armatures A and B; a Hall sensor A and a Hall sensor B are symmetrically fixed on the pump shell and are towards the pump shaft; an annular permanent magnet A and an annular permanent magnet B are symmetrically fixed at the middle part of the pump shaft, and between the axial positions of the Hall sensor A and the Hall sensor B; the coil A and the coil B are electrified and produce magnetic force; when the Hall sensors A and B respectively sense with the annular permanent magnets A and B, the electrification directions of the coils are reverse, and the pump shaft is driven to suction and drain liquid back and forth and left and right. According to the bidirectional electromagnetic diaphragm pump, the flow of the pump can be increased by suctioning and draining liquid with double pump heads in sequence, the double pump heads suction and drain liquid alternatively and the flow pulsation can be reduced, and the efficiency of the pump can be improved by driving with the bidirectional electromagnet instead of a motor.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic diaphragm pump manufacturing, in particular to the field of a bidirectional electromagnetic diaphragm pump. Background technique [0002] The current types of diaphragm pumps can be divided into pneumatic diaphragm pumps powered by compressed air, hydraulic diaphragm pumps powered by hydraulic oil medium, and electric diaphragm pumps powered by electricity. Among them, pneumatic diaphragm pumps and hydraulic diaphragm pumps need attached air compressors and hydraulic pumps and other devices, which are large in size and limit the installation space; electric diaphragm pumps can be divided into motor-driven diaphragm pumps and electromagnet-driven metering pumps. , The motor-driven electric diaphragm pump has complex structure, low mechanical efficiency, and is easily affected by power supply voltage and frequency. The electromagnet-driven diaphragm pump replaces the motor part with an elect...
